IMPROED SPRING-ADJUSTER.

` The Schedule referred to in these Letters Patent and making part ofthe same;A

To all whom it 'ma/y concern.-

Be it known that I, J AMES D. VAN HoEvENBnnGH, of Kingston, in thecounty of Ulster, and State of New York, have invented a new andimproved Spring-Adjnster for carriage and othersprings; and I do herebydeclare that the following is a full. and exact description thereof,reference being had to the accompanying drawings making part of thisspecification, and repre:

senting a side view of a wagon, with the spring-'adj uster applied toone of its springs. l

The purpose of this instrument is to take the bend out of carriage andother springs when bent, or to re- Set them into form, when sprung outof shape. The

instrument eii'ects this purpose on carriage and wagon plied to thespring, for the llink fto bear upon, so as not to strain the spring atthat place.

A movable bloclg, h, is applied between thelever and the bent part ofthe spring. The other end of the lever extends through or is attached toa block lm.,

which slides up and down on the shank of a hook, i,- .which is hookedaround thespring, or som'e other sup@ The hook has port, in the properposition for action. a screw-thread, l, onits shank,and a nut, n, (witha handle, if preferred,) to turn thereon. On turningv the nut, the leveris operated, exerting a powerful action on the spring where the block hbears, sufficient to reset it into its proper form. The instrument isthen readily removed. Y

The adjuster is simple, inexpensive, and readily applied, and issuiciently compact to be carried about with a wagon, when occasion'rnayseem to require.

XVhat I claim as my invention, and desire to secure by Letters Patent,is

The improved spring-adjuster above described, its-V several parts beingarranged, andl operating together, substantially as herein specified.

The above speciiication of my improved spring-ad?.

juster, signed by me, this 15th day of May', 1868.
